The vermillion grisette, also known as pretty grisette or vermilion Amanita is a colourful mushroom of the genus Amanita. However, although it is often referred to by the common name "grisette", it is not closely related to other edible species that carry this common name, such as Amanita vaginata and Amanita fulva. It belongs to the same group of Amanita as Amanita muscaria and is reported to be toxic.

There is one report of a person being quite ill after tasting a small piece of it in 1997.

Amanita xanthocephala lives in an ectomycorrhizal relationship with Eucalyptus.
